Genetically-mutated bacterial strain for detecting estrogenic compound and method for detecting estrogenic compound using the same

The present invention relates to a genetically mutated bacteria strain for detecting an estrogenic compound and a method for detecting an estrogenic compound by using the same. More specifically, the present invention relates to a bacteria strain having an ability to detect an estrogenic compound, transformed by plasmid A comprising base sequences in which a gene for encoding a coactivator interacting with an estrogen receptor ligand binding domain (ER LBD) is conjugated to a gene for encoding λCI protein, and plasmid B in which a gene for encoding an estrogen receptor ligand binding domain (ER LBD) is conjugated to a gene for encoding αNTD protein, and a method for detecting an estrogenic compound by using same. The present invention can provide genetically mutated bacteria for detecting an estrogenic compound and a method for detecting an estrogenic compound by using same since the bacteria are based on estrogen receptor protein originated from the human body, and thus are environmentally friendly, and the detection of the bacteria can be performed in a very short time with low cost and labor by virtue of a relatively simple process.

Recombinant <i>Escherichia coli </i>and application thereof in screening erythritol-producing strains

The present disclosure discloses recombinant Escherichia coli and application thereof in screening erythritol-producing strains, and belongs to the technical field of microorganisms. The recombinant Escherichia coli used in a method for screening an erythritol-producing strain disclosed by the present disclosure can well perform positive correlation induction on erythritol with different concentrations, so that the method for screening the erythritol-producing strain has the advantage of high sensitivity. High-concentration glucose is usually adopted as a fermentation substrate when erythritol is produced in a fermentation mode in the industry, but the method for screening the erythritol-producing strain disclosed by the present disclosure can overcome the interference of the high-concentration glucose, and under the interference of the high-concentration glucose, the recombinant Escherichia coli used in the method for screening the erythritol-producing strain can still well perform positive correlation induction on erythritol with different concentrations, and the correlation is higher than that without the interference of the glucose. Therefore, the method for screening the erythritol-producing strain has the advantage of strong anti-interference capability.
